BOM margins

The first thing is that you can drag the borders and control how the text wraps. As far as reducing the min space before or after the heading, I don't know of a way. If you want to remove the config name from the Qty. field, double-click in the cell, delete the config name text, and also the period at the end. If you leave the period, the config name will reappear.

You can reduce the column width by right-clicking on the column, then choose Formatting - Column Width. In this way you can reduce the width, but if you start dragging the column-width will be (to) wide again. \/\/im

I found the border dragging OK and it can be quite usefull, if I have a long blurb in the 'Description' column, to be able to force a wrap. Its the 'Item' & 'Qty' columns that only have two digits in them that take up about 50% more width than necessary because of the set margins. As A3 is the max size sheet used & space can be at a premium.
